E0 is a common Daikin furnace error code. It can be caused by many different things. Here are some of the most common causes:
The gas valve needs to be replaced
The gas valve is defective and needs to be replaced
There is an obstruction in the gas pipe next to the gas valve and it needs to get fixed or removed
The flame sensor is defective and needs to be replaced

Daikin has a range of high quality products that are engineered specifically to suit different types of needs. They offer energy efficient products with a guaranteed return on investment and they also provide excellent customer service and 24-hour service support. However, their products come with the Daikin warranty which ensures safety, comfort, and peace of mind for their customers.
Daikin air conditioning systems are designed for residential, commercial or industrial use. They have built in functions that cool down or heat up the air depending on the user’s requirements. This Daikin furnace error code e0 is quite common in these systems and it is an indication of insufficient oxygen levels in the system’s furnace which can cause serious damage to other components.
"Inspections, Installations, Repairs & Maintenance"
If you are considering furnaces, this guide walks through the key technical and practical points specific to Metro Vancouver. Daikin is Japanese (Osaka, 1924, world's largest HVAC manufacturer), best known for its FIT inverter heat pump (slim-profile), VRV multi-zone, and Daikin One+ smart thermostat. The brand's strengths are inverter technology pioneered by Daikin, excellent dehumidification, integrated Goodman engineering since 2012 acquisition.
Vancouver's moderately hard tap water (around 60-100 ppm hardness in most of Metro Vancouver) affects tankless water heaters, combi boilers, and hot-water tanks — annual descaling is essential. CANRO has worked with Daikin systems across Metro Vancouver since 1999, from older retrofits in Newton and Edmonds to new builds in Burke Mountain and Thompson. Daikin is generally a strong fit for whole-home ducted heat pump replacements and homes wanting Mitsubishi-tier performance at a slightly lower price.
Sizing. Proper furnace sizing requires a Manual J load calculation — most Vancouver homes need 50,000-90,000 BTU, but oversized furnaces short-cycle, accelerate component wear and produce uneven temperatures.
Lifespan. A well-maintained high-efficiency gas furnace lasts 15-20 years in Vancouver. The single biggest factor in lifespan is annual professional servicing — combustion analysis, condensate trap cleaning, and igniter inspection prevent 80% of mid-life failures.
Warning signs. A failing furnace usually announces itself: short-cycling, yellow flame (should be blue), rising gas bills, uneven heating between rooms, banging on startup, or persistent error codes on the control board.
Over 25+ years of Daikin service calls across Metro Vancouver, the recurring issues we see are: communication faults on the Daikin One+ thermostat, condensate-pump installs in attic locations, ECM motor failures past 10 years.
Parts availability. Daikin parts are increasingly available locally thanks to the Goodman parts depot integration.
Two-stage furnaces (high/low burner) are a good fit for most Vancouver homes — they cut short-cycling and run quieter than single-stage units. Modulating furnaces (continuously variable burner output) are worth the premium in larger homes (3,000+ sq ft), homes with significant temperature zones, or homes prioritising the absolute quietest operation.
A typical residential high-efficiency gas furnace installation in Metro Vancouver costs $4,500-$8,500 including the equipment, venting, gas-line work, permit, electrical, and removal of the old unit. Variable-speed and modulating models are at the upper end. CANRO provides three quote tiers (good/better/best) so you can choose the right balance for your home and budget.
Yes — for most Metro Vancouver homes, a cold-climate heat pump alone provides 100% of heating needs down to -10°C. Some homeowners choose a dual-fuel setup (heat pump + small gas furnace as back-up for the rare deep cold snap), but this is rarely necessary in our climate.
Short-cycling typically indicates one of: an over-sized furnace for the home, a dirty flame sensor, a clogged condensate drain triggering shutdown, low gas pressure, a failing limit switch, or a thermostat located in a non-representative spot (in direct sunlight, near a vent). All are diagnosed quickly during a service call.
Yes. Annual professional servicing catches 80% of mid-life failures before they cause a no-heat call. It also keeps manufacturer warranties valid — most are voided by missing scheduled maintenance. The service includes combustion analysis, heat-exchanger inspection, flame-sensor cleaning, blower-motor check, condensate-trap clearing, and a full safety test for carbon monoxide.
For Metro Vancouver homes, 95-97% AFUE is the sweet spot — high enough to qualify for FortisBC rebates and capture nearly all available efficiency gains, but without paying a premium for the very last 1-2% from 98% AFUE modulating units. ENERGY STAR-certified models above 95% AFUE are required for current rebate programs.

“Canro does an amazing job! Super professional and skilled with everything—boilers, furnaces, and AC. Always a pleasure working with them!”
“Five stars for Canro. We needed a replacement of a 30-year-old boiler. A new high-efficiency unit was installed—clean, professional work.”
“I can’t speak highly enough about George, who was recommended for a boiler service call for my parents’ home. George is excellent.”
